The Noise Level of Metal Roofing Explained: L&N Construction

Will a metal roof turn your home into a drum during a Colorado Springs hailstorm? It is the single most common question homeowners ask about metal roofing, and the short answer is no -- not with modern installation techniques. Here is why.

Is Metal Roofing Really That Loud?

The "loud metal roof" reputation comes from old agricultural buildings -- pole barns and sheds where metal panels are fastened directly to open rafters with no insulation or decking underneath. In that setup, every raindrop and hailstone resonates through the building.

A residential metal roof is a completely different assembly. When installed over solid plywood or OSB decking with synthetic underlayment and proper attic insulation, a metal roof measures only 3-5 decibels louder than asphalt shingles during heavy rain. That is barely perceptible to the human ear.

What Actually Makes Metal Roofs Noisy

Noise in metal roofing comes from three sources, all of which are controllable:

• No solid decking: Metal fastened directly to purlins (spaced framing) creates a drum effect. Residential installs over continuous plywood decking eliminate this.
• Insufficient insulation: Attic insulation absorbs sound transmission. Colorado Springs homes in climate zone 5 should have R-49 attic insulation per the 2021 energy code -- that much insulation is a serious sound barrier.
• Exposed fastener panels: Screw-down panels (common on commercial buildings) can tick and pop with thermal expansion. Standing seam systems with concealed clips allow the panels to float and expand silently.

Real-World Noise Comparisons

Independent testing puts the numbers in perspective:

• Asphalt shingles during heavy rain: ~46 decibels inside the home
• Metal roofing during heavy rain (over decking): ~49-52 decibels inside the home
• Normal conversation: ~60 decibels

During a typical Colorado Springs afternoon thunderstorm, the difference between metal and asphalt is essentially inaudible over the sound of the rain itself.

Proven Noise Reduction Techniques

1. Solid decking: 7/16" OSB or 1/2" plywood minimum. This alone cuts noise by 50% compared to open-frame installation.
2. Synthetic underlayment: An additional layer between decking and metal that dampens vibration.
3. Attic insulation: R-49 blown-in or batt insulation. Fiberglass and cellulose both work well for sound absorption.
4. Standing seam panels: Concealed fasteners and floating clips eliminate thermal expansion noise. This is our recommended system for Colorado Springs homes.

Metal vs. Shingle Roofing: The Full Picture

Noise is just one factor. Here is how metal and asphalt compare across the metrics that matter most in our climate:

• Lifespan: Metal lasts 50-70 years vs. 20-30 years for architectural shingles. At 6,035 feet elevation with 25% more intense UV, shingles degrade faster than at sea level.
• Hail resistance: Metal panels rated to Class 4 withstand 2-inch hailstones. After a major hailstorm, metal roofs typically need zero repairs while shingle roofs need full replacement.
• Energy efficiency: Metal reflects solar radiation, reducing cooling costs by 10-25%. With 300 sunny days per year in Colorado Springs, that savings compounds.
• Cost: Metal costs $15,000-$30,000 installed vs. $8,000-$15,000 for shingles. But when you factor in one metal roof lasting as long as two or three shingle roofs, metal often wins on lifetime cost.
• Insurance: Many Colorado insurers offer premium discounts for Class 4 metal roofing systems, similar to impact-resistant shingles.

Making Your Decision

If noise has been holding you back from considering metal, rest assured that a properly installed residential metal roof is virtually indistinguishable from shingles during storms. The performance advantages -- especially in a hail-prone area like the Pikes Peak region -- make metal worth serious consideration.
